WILLIAIII HCDGSON AND EDWARD J. DE-EGAN, OF NEW YORK, N. Y.

REGULATOR.

To all whom it may concern:

Be it known that we, WILLIAM Hoooson and EDWARD J. DEEGAN, citizens of the United States of America, residing at the city of New York, in the State of New York, have invented certain new and useful Impro-vements in Regulators, of which the following is a specification.

Our invention relates to regulators and consists in the peculiar construction of the same, as hereinafter described and as more particularly set forth in the claims.

Figure 1, is a vertical sectional view of the regulator embodying our invention. Fig. 9., is a plan view of the cover and the lever sup porting bracket. Fig. 3, is a plan view of the bracket blank. Fig. 4, shows two halves of the weight we prefer to use.

1, represents adished base for a regulator, provided with a threaded nipple 2, adapted to be screwed on to a steam pipe or some analogous connection of the system to be regulated. The base 1 is of considerable rigidity, though preferably constructed of sheet metal, and has a rim 3, the upper and outer faces of which are of no greater angle than a right angle, one to the other.

4, is a diaphragm, preferably corrugated in concentric circles and extending over the upper and down against the outer side face of the rim 3, of the base.

5, is the cover, of sheet steel, with a central aperture surrounded by a flange 7, which eX- tends upward and outward over and upon the collar 8, which is passed over the flange, before it is forced down over collar 8, and which, when the flange is forced down over it, is thereby held in position upon the cover 5, but free to revolve around the still upright part of the flange 7 At the outer edge, the cover is flanged, as at 9, and the flange fits with extreme closeness over that edge of the diaphragm which is against the outer face of flange 3. The parts are secured together by a tremendous hydraulic pressure, 9 being sometimes heated at the time, and this pressure is so great as to create a steam tight joint between flange 3, the diaphragm 4, and the flange 9, the cover just within said flange being also forced down so tightly upon that part of the diaphragm overlying the upper face of flange 3, as to clamp it tightly to said upper face of 3, and aid greatly in perfecting and maintaining the tightness of the joint. On a line concentric with the center Specification of Letters Patent.

of the aperture 6, the cover is also pressed or forced upward so as to constitute a circular rldge or projection 10, upon which the bracket, integral with collar 8, may ride.

The extensions shown in the blank of the collar piece, are turned upward to constitute the bracket or cars 11, which are pierced to receive a bolt 12, which passes through the said ears or bracket and acts as a pivot for the lever 14, which is thus permitted a limited vertical movement. Seated upon the diaphragm 4, extending up through aperture 6, and bearing against the under side of lever 14, is a post 15, by means of which the upward movement of the diaphragm is communicated to the lever. In this form of the device, vve make the ears of the bracket 11, long enough to provide for the pivot of the lever 14, and also to sustain a pivot for an arm 16, carrying a weight 17 to be used in adjusting the regulator to operate at the de .sired temperature.

The ball is preferably made in hemispherical form, each half slotted, as at 18, to fit over the lever, and a circumferential groove 19, is formed about both halves, preferably at right angles to the line of partition. A coil spring 20, located in groove 19, will hold the parts together and press them upon the lever with suflicient force to hold the ball in that position where it is manually placed. The purpose of thus pivoting the weight, is this: At times it is desirable to lift or depress the lever further than the diaphragm movement would do, or to hold it temporarily in a given position. By mounting the weight as described, it is extremely easy to swing it over to that side of the lever which is to be depressed and slide it out far enough to assure the maintenance of the depression for the desired time.

This regulator may be struck up from sheet metal. It may be assembled and its proper arrangement maintained without the use of bolts or nuts or other extraneous de' vices to hold the base, diaphragm and cover together, and its construction, as described, produces a very effective, economical and durable article, so low in cost that when a partfor instance the diaphragmdoes wear out, the entire article may be discarded and a new one substituted.

Our main discovery is the fact that the parts may be sufficiently fastened together by pressure, a thing we have succeeded in doing, though it was not heretofore known that the required joint could thus be made suiiiciently tight to be and remain a steam tight oint when subjected to continuous and varying pressure, sometimes of high degree, such as a regulator must be able to sustain.

Another feature is the swiveling of the le ver support about a given center of the fluid holding part of the device. Still another is the arrangement for shifting the Weight from one side of the lever pivot to the other. These levers are to be set so as to extend in a given line, in order that they may be properly connected to the valve or other device which is to controlled. When the bearings are rigidly secured to the base, then that may not be turned down on the pipe sufiiciently tight when the lever registers with the appropriate line, but, with our arrangement, the base may be screwed on to the pipe as tightly as desired, even With the lever in position, or without it, and the bracket piece may swing during the movement, the lever remaining in the proper line, or the bracket piece may be brought to that line afterward and then equipped with the lever. This op eration of the lever is facilitated by the circular rib or fin 10, which furnishes a rest for the lever in its movement.

WVhat we claim and desire to secure by Letters Patent, is

1. A regulator composed of a dished base provided with means for securing it to a fluid conducting pipe, and a rim, a diaphragm extending over the dished part of Copies of this patent may be obtained for the base and the rim, a cover of steel plate with a flange at its edge, pressed so tightly upon the rim of the diaphragm and the base as to form a steam tight joint therewith, together with a lever and means for transmitting the movement of the diaphragm to the lever, all substantially as set forth.

2. A regulator composed of a dished base provided with means for securing it to a fluid conducting pipe, and a rim, a diaphragm extending over the dished part of the base and the rim, a cover secured to the base and holding the diaphragm between, an aperture through said cover, a lever sustaining bracket swiveled about said aperture, a lever pivoted in said bracket and means for transmitting the movement of the diaphragm to the lever, all substantially as set forth.

A regulator provided with a pivoted arm carrying a weight, arranged as described, to rest upon the lever and adapted to be swung to the respective sides of the lever hearing, all substantially set forth.

In testimony whereof, we have signed our names to this specification in the presence of two subscribing witnesses, this 2st day of November, 1913.
